## Issue Addressed
NA
## Proposed Changes
There was a regression in #3244 (released in v2.4.0) which stopped pruning fork choice (see [here](https://github.com/sigp/lighthouse/pull/3244#discussion_r935187485)).
This would form a very slow memory leak, using ~100mb per month. The release has been out for ~11 days, so users should not be seeing a dangerous increase in memory, *yet*.
